The list of gw product that were totally teribble on the realese is much bigger than being op ones. Heck last of them, Kragnos is quite useless. Slow, no mortal wound protection, ez to block, very expensive. More examples: Vanguard chamber wave. Only vanguard raptors and birds were played. Entire CSM range get refreshed to be still useless. Theory that gw make op new models is tin foil hat theory. I can give you more examples if you want.
